Androgen excess in women is associated with the development of PCOS and its abnormalities. The Hypothalamus Pituitary Ovarian axis signaling is altered with excessed androgens, leading to anovulation and infertility. Previous studies in the lab have shown that AR signaling in the pituitary alters gonadotrophin release. Hence, the present pioneering study was an approach to determine the transcriptomic changes responsible to the phenotype seen with DHT excess. RNA seq data showed that 583 genes were differentially regulated by DHT in pituitary, of which 344 were upregulated and 239 downregulated. Pathways involved for these genes included endoplasmic reticulum, Golgi apparatus, calcium signaling and vesicles. Meanwhile, Transcriptional factor analysis showed that majority of the genes changed had Androgen responsive elements.
